y HAND BRUSH.

Application filed March 15, 1927. Serial No. 175,607.

back, for reinforcing or strei'igthening the back against distortion bylthe expansive force of the bristles in their sockets when wet, and thusprevent theformation of a hollow in the middleof the back for thecollection of water to prevent quick drying ot the bristles, as withbrushes as heretofore made.`

Another object of my invention is to provide the metal back withopenings extending therethrough along the sides of the back exterior ofthe bristles for draining water ofi' the upper surface of the back orquick drying of the bristles.

Other and further objects oil my invention will appear from thefollowing specication taken in connection with the accom panyingdrawings, in which- Fig. l is a top plan view of my improved hand brush;

F ig. 2 a side view of the saine;

Fig. 3 is an enlarged vertical sectional view taken on line SMS of Fig.l; and

Fig. et is a fragmentary vertical sectional view'on line i-4l of Fig. 8.

As shown inthe drawings, my improved hand brush has a. back l,preferably die-cast from white o'r like metal an d given. generallyrectangular form. Said back l is provided in its under side ywith aplurality of sockets or cavities 2, 2 to receive the folded upper endsof tuftsy of bristles 3, 8. The sockets or cavities 2, 2 are preferablyarranged in a plurality of substantially parallel rows eX- tendinglengthwise of thel back.

The back l has holes or apertures 4l, l opening into the sockets fromthe upper side of the back, so that loops 5, 5 of a wire 6 may extendinto the sockets and engage under the folds in the bristles for holdingthe same tightly in the sockets, as shown in Figs. 3 and 4.-. The wire 6lies in grooves 7, 7 in the upper surface of the back l over andfollowing the rows of sockets, as shown.

rl'he folded upper ends of the tufts of bristles 3, 3 substantially fillthe sockets or cavities 2, 2, so that the bristles may be held tightlyin the sockets and thus notA loosen and fall out in the use of thebrush. Vvlhen wet, the folded upper ends of the bristles expand and incast metal backs as heretofore designed, the backs have been distorteddownward in their midportions, forming hollows for water to collect andprevent quick drying of the bristles.

To overcome this objection, I cast upright flangesS, 8 along theopposite sides of the back l, as shown in the drawings. Theser ianges 8,8 project above the upper surface of vthe back and extend substantiallythe full length thereof and reinforce or strengthen the back againstdistortion when the folded upper ends of the bristles expand in theirsockets 2, 2 when wet. The side portions 9, 9 of the back between theoutermost side rows of bristles 3 and the flanges 8 are inclineddownward from the flanges, and each is provided with a row of holes oropenings l0, l() extending therethrough exterior of the bristles fordraining water off the upper surface of the back `l for quick drying ofthe bristles. The back l over the bristles is in ellect solid for theholes 4 are closed by the wire loops 5k and would not allow the channelformed by the back l and flanges 8 to drain if it were notfor theprovision of the holes l0. These are an important feature of niyinvention because they prevent water collecting on the back toy hinderdrying of the bristles.

The upright flanges 8, 8 form hand grasping portions at the sides of theback so that the brush may be readily picked up and handled while inuse. To prevent slipping ot the lingers oil these flanges 8, they arecorrugated along the outer side surfaces by means of a plurality ofgrooves ll, 1l, as shown in F 2 and 3.

The details of structure shown and described may be variously changedand modirfied without departing from the spirit and scope of myinvention.

I claim as my invention:

l. A hand brush having a cast metal back having a relatively thin ilatbody provided with a plurality of sockets in its under side, bristlessubstantially illing said sockets, means holding' the bristles therein,and upright flanges cast on the body alongthe opposite sides thereof andextending above the saine, said flanges providing hand grasping portionsfor the body and also strengthening the body against distortion by theexpansive force `of the bristles in the sockets when wet.

2. A hand brush having a cast metal back having a relatively thin flatbody provided with a plurality of sockets in its under side,

bristles substantially filling said sockets, ineans holding the bristlestherein, and upright iianges cast on the body along the opposite sidesthereof and extending above the saine, said flanges forming with thebody an upwardly opening channel, said back having a plurality ofopenings extending therethrough for draining said channel.

3. A hand brush having a east niet-al back with a. plurality `of socketsin its under side bristles substantially filling said sockets, andmea-ns holding the bristles therein, said back having its side portionsextending beyond the bristles and extending upward to provide ith theback an upwardly opening channel, said back having a plurality of drainopenings in its side portions exterior of the bristles.

el. A hand brush having a cast metal back with a plurality of sockets inits under side, bristles substantially filling said sockets,

means holdinO' the bristles therein and u rright langes cast on the backalong the opposite sides thereof, said anges providing grasping portionsfor the back and being corrugated along their outer sides.

5. A hand brush having a cast metal back with a plurality of sockets inits under side, bristles substantially filling said sockets, and inea-nsholding the bristles therein, said back having its side portionsinclined upward and terminating in upright flanges, said inclinedportions having a plurality of drain openings extending therethroughexterior of said bristles.

6. A hand brush having a cast inetal back with a plurality of sockets inits under side, folded tufts of bristles having their folded endsinserted in and substantially filling said sockets, wire loops engagingthe folded portions of said bristles holding the saine in said sockets,and upright flanges cast on the back along its opposite sides, said backhaving drain openings extending therethrough inside of and along saidflanges.

ln testimony whereof I aiiiz; iny signature this 9th day of March, 1927.
